Would there be a down side to always doubling your bolts?

I suppose that answer is similar to my question about why brass nuts are used for hpc in another thread, which @Zack_illuminated answered and that is to give a place for failure to happen.
if you inspect and replace your nuts often you will likely have no issue or need to double.

I use doubles on anything over 4” but i run alot of propane and nothing bigger than 8”

Thanks man I think I’m gonna do that to. I don’t run crazy high pressure but I push with about 50 psi of nitro so its not nothing
tightening them. does lexus double nut stuff? I guess a bho machine is more stress than a suspension. If 2 nuts is good 3 nuts is better… SAFETY
Does a Lexus get disassembled and reassembled daily? Check your nutz, two are better than one 
Come on thump, double nuttin’s good safe fun!

Its a cheap piece if mind, new ones every 2 weeks all torqued

Its really not necessary to use much more pressure than is required for your solvent to be forced to the liquid phase.
Would’ve been better bleeding the gas from the recovery port under the fume hood before trying to open it.
If communities actually existed outside of being Amish then yes, it would be possible. It’s because communities aren’t real, they’re not close or have an all for our community attitude.
-going political real quick-
The globalist agenda to make people more focused on the world rather than where they come from is what’s going on. Like eventually the conversation or debate of “Is it nationalist to have a mayor?,” will happen. …
It’s also because people hate where they come from and tend to not care about it either and just live in the areas they live in
… Maybe that’s just Massachusetts but it’s disheartening to know that not many people identify with what city or town they come from and don’t get involved in local politics.
example :Biden isn’t going to fix the Greater Boston area only the mayor’s of those cities will.

We run 100% propane all the time and only double up if there is a leak and you need to tighten while pressurized.
There should always be an intended fail point or weak spot that minimizes the potential damage from failure. If it were the bolt or clamp that failed instead, there would be much more excitement in the room.

Yes. Two nuts works.
Two bolts is for dolts

I’d be more worried about your standard operation procedure of torquing the nuts to “50.”

My girlfriend always says this, but I find myself spent after just one nut. Wait, what are we talking about.

I was told to torque all my HPC to 5ft/lbs or 60in/lbs. This is typically the point the nuts begin to squeak. Had some small leaks below -30F. Never run a racked system before this so just going with the manufactures specs. Tried to tighten to 25ft/lbs and the 6" clamps almost touched, couldn’t even get all the way to 25 I believe.
That’s because the gaskets are squished and need replaced or the clamps are stretched and need replaced. Start with gaskets then if they still touch replace the clamps.
I spent a good amount of time looking the other day and most manufacturers either don’t state a torque rating or some state 20ft-lbs for (13MHP) high pressure clamps 13MHP.
If you clamps touch before reaching 20ft-lbs you should stop and replace the gasket or clamp.
I personally find 20 ft-lbs isn’t enough to pass a pressure test with new gaskets and clamps when fluctuating temps upwards of 80-100 degree Celsius.
I have also found different gaskets require different torques so i wouldn’t rely on 20ft lbs but you should figure this out on your own with pressure tests and your own system.

Was brand new gaskets and clamps, using buna gaskets.
Pressure tests hold fine, will have to try a higher torque on the next cold run and see if that same column keeps leaking.
If you have a continual leak from the same column I would stop running and do a pressure test without gas and figure out why it’s still leaking.
Take a straight edge to your sealing surfaces and ensure the tri clamp ferrules are flat.
Tuf steel gaskets are designed for extremely large temp fluctuations from higher and lower than our standard temps.

Gylon gaskets work better than the tough steel ones, too
